This project aims to form a collaboration between Queen's University with AAVAA Inc.AAVAA Inc. is developing hearing aids with capability of attention detection decoding by recording and analyzing brain waves. The brain waves are recorded non-invasively through the skin around the ear and within the ear canal. The system analyzes recorded brain waves known as electroencephalograms using Advanced Audio Signal Processing and Artificial Intelligence (AI) algorithm, developed by AAVAA, and focuses on and amplifies the sound that the user wishes to attend to without relying on any manual intervention.One of the main components of this system contributing to recording electroencephalography signals (brain waves) is its electrodes. Electrodes are interfaces between the system and skin.The goal of this project is to develop dry soft sensors that can form stable and conformal contact to the skin around the ear and within the ear canal for reliable long-term recording of brain waves. Our goal is to address one of the main challenges in the field of biosignals recording using dry electrodes which is minimizing and avoiding motion artifacts and reducing skin-electrode interface impedance.We aim to achieve this goal through utilizing novel materials such as nanomaterials and innovative engineering design.

该项目旨在形成皇后大学与AAVAA公司之间的合作。正在开发具有通过记录和分析脑电波来检测注意力解码能力的助听器。脑电波是通过耳周围和耳道内的皮肤非侵入性地记录的。该系统使用由AAVAA开发的高级音频信号处理和人工智能（AI）算法分析记录的脑电波（称为脑电图），并在不依赖任何人工干预的情况下集中并放大用户希望注意的声音。该系统的主要组件之一是记录脑电图信号（脑电波）的电极。电极是系统和皮肤之间的接口。本项目的目标是开发干燥的软传感器，该传感器可以与耳周围和耳道内的皮肤形成稳定和适形的接触，以可靠地长期记录脑电波。我们的目标是解决使用干电极记录生物信号领域的主要挑战之一，即最大限度地减少和避免运动伪影并降低皮肤电极界面阻抗。我们旨在通过利用纳米材料等新材料和创新的工程设计来实现这一目标。
